Stop AI agents from acting on bad outputs.

Agent Verifier gives autonomous workflows a strict pass/fail confidence layer before they write to CRMs, send emails, call tools, or trust generated records. New CRM-ready and lead-score endpoints help stop bad AI-generated leads before they pollute your pipeline.

AI agent verification API for autonomous workflows

Agent Verifier is an AI automation guardrail and agent output validation API. It gives AI agents, MCP tools, n8n workflows, lead-generation bots, and SaaS automations a machine-readable checkpoint before they act on generated data.

Use the OpenAPI schema to connect agent frameworks and developer tools directly: /openapi.json. AI agents can also read the compact discovery file at /llms.txt.

Bulk CSV Lead Cleaner

Paste or upload AI-generated lead lists, score every row, and download verified.csv, needs_review.csv, and failed.csv before importing to your CRM.

CRM-ready lead checks

Validate company, website, email, required fields, placeholder values, and domain alignment before writing to HubSpot, Salesforce, Airtable, Sheets, or GoHighLevel.

Lead quality score

Return a 0–100 lead score with risk level, missing fields, issues, warnings, and a machine route: write_to_crm, queue_human_review, or do_not_write.

n8n workflow template

Use the included n8n template to put Agent Verifier between an AI lead-gen agent and your CRM in minutes.

Verify generated JSON

Catch malformed records, missing fields, schema mismatches, and unusable tool-call payloads.

Check URLs and emails

Confirm reachability, HTTPS, expected page text, email syntax, and optional DNS hints.

Score agent output

Require terms, forbid risky phrases, enforce JSON/plaintext formats, and return machine decisions.

First monetizable use case: lead-gen agent guardrail

Agent finds a lead → Agent Verifier checks JSON, company URL, email, and required fields → only safe records get written to CRM. Uncertain records go to human review. Failed records get regenerated or discarded.
